COMBINATION GRAIN CUTTING AND ELEVATENG MACHINE.

Application filed. December 9, 1920.

To all whom it may concern:

Be it known that l, DENNIS C. VAN BUREN, of the town of l Vilkie, in the Province of Saskatchewan, Canada, have invented certain new and useful Improvements in Combination Grain Cutting and Elevating Machines, of which the following is the specification.

The invention relates to improvements in combination grain cutting and elevating machines, the object of the invention is to provide a machine wlrch will effectively cut the standing grain and elevate and discharge the same and embodies as distinctive features in its construction stationary concentrically ranged knives and rotary cutter acting in and utilized to deliver the cut grain to a pickup appliance which gathers the grain from the cutter and feeds it to a discharger which delivers the grain in windrows at the back of the machine.

A further object of the invention is to construct the various parts of the machine in a simple and durable manner and so that the Whole can be readily assembled and such that the various cutting knives and blades are interchangeable.

lVith the above more important and other minor objects in view. which will become more apparent the description proceeds, the invention consists essentially in the arrangement and construction of parts herein after more particularly described and later V ence being had to the accompanying drawings in which Fig. l is a plan view of the complete machine.

Fig. 2 is a front view thereof.

Fig. 3 is a sectional view through the machine showing the discharger and parts associated therewith in side elevation.

l ig. at is a plan view of the table.

Fig. 5 is an enlarged detailed vertical sectionalviewthrough the table and the rotary cutter showing the blades and knives, the section being taken at 5-5 Figure 1.

Fig. 0 is av detailed sectional view at 66 Figure 1 through the driving gears of the discharger.

In the drawings like characters of reference indicate corresponding parts in the several figures.

l is a substantially rectangular frame onjunctlon with the knives to cut the grain pointed out in the appended claims, refer-' formed from inter-connected side and end members, the said frame having the rear end supported by a comparatively large wide rimmed master wheel 2 and the front end supported by an angularly disposed flanged ground wheel 3 which is adapted to offset the side draft occasioned by the grain cutting parts of the machine.

t represents the axle of the master wheel which axle is utilized as the driving shaft of the machine.

"lo the side of the frame 1, I connect a table indicated generally by the reference nuieral i and which embodies as part of its ucture connecting arms 6 and 7 attached 0 the binder fi 111.116 a plurality of beams 8 from a central hub like bearing 9 c. a plurality of arcuate beams 10 con mined in the horizontal plane and arranged concentric to the bearing and forming what might be termed a circular carriage which titted at intervals with carriage wheels 11.

The table is supported by a rearwardly disposed carriage wheel 1:2 attached to the rear end of one of the beams 8 which eX- tends rearwardly and by a forward carriage wheel 13 attached to a front bracket lt'secured to the carriage 1O.

15 is aswath board located in advance of the wheel 13 and carried in any suitable manner such as by extending the axle of the wheel and attaching the board to the inner end of the axle.

As will be observed this swath board is adapted to part and direct the standing grain towards the table. To the table I attach also a rearwardly disposed bracket 16 similar to that 14, the object of which Will be later explained.

To the front part of the carriage I permanently secure a plurality of similar radially disposed cutting blades 1'? which are arranged side by side and have their exposed or forward ends ll-shaped. l hese cutting blades really form a stationary arcuate cutting bar across the front of the table.

18 is an elevated hub like hearing positioned above and aligned with the'bearing 9 and located at the juncture of five radiating arms 20, 21, 22, 23 and 24 tie outer ends of the arms 20, 21 and 22 being downturned and secured to the frame structure whilst the outer ends of the arms 23 and 24 are downturned and secured to the brackets 14 and 16 which support them.

nected to the inner end of the shaft 29 by a universal joint 33 and the other end connected to the end of the shaft at by a universal joint 34. Obviously the master wheel will effect the driving of the shaft as the machine is advanced by draft animals hitched to the front of the same.

To the lower end of the shaft 25 I secure permanently a rotary cutter 35 which is in the form of a slightly coned disc 36 fitted at the outer edge with a plurality of similar cutting knives 37 and provided on the upper face with sets of radially disposed wedge shaped dividers 38.

The cutter is positioned directly above the carriage and it has a Somewhat smaller radius and the rollers 11 are adapted to ride the underside thereof.

The knives 37 are all similarly constructed and are fastened to the edge of the disc by riveting as indicated at 39 and thev all present a curved cutting edge 40 which is adapted to sweep across the cutting edges of the underlying cutting blades in the rotation of the disc and they are all provided with an underlying extension 41 which passes underneath the cutting blades. The dividers 38 rows, and are adapted to part the grain falling on to the disc and gather it so that it will lie more or less radially on the disc.

In order to positively bend and thrust the grain back soit will fall on the table, I have provided a deflector 37 associated with each knife 37 the deflectors in the present instance each being in the form of a stout wire having its forward end secured to the tip of the knife and then bent upwardly and backwardly and terminating in an ele vated position above the edge of the table. It is to be noticed also that the deflectors are curved in advance of the knife (see Fig. 1), the arrangement being that they bend the standing grain in advance of the knife so that it is positively bent towards the table and will fall thereon when out.

Rearwardly of the machine and above the cutter I locate a discharger which embodies a plurality of pickup prongs 42, the forward tips of which ride the top face of the disc and an endless toothed conveyor 43 positioned above the prongs and adapted to positively feed the material gathered by the prongs rearwardly and on to the discharge deck 44:.

The discharge deck 4 1 is supported by a bracket 45 from the table and the prongs are positioned to ride in between the dividers 38 as the cutter rotates.

The toothed conveyor 13 is carried by suitable side bearings attached to the bar 21 and a bar 46 extending between the bar 22 and that The shafts 4LT and 18 of the con veyor which are mounted in the latter bearings are provided with chain wheels connected by a chain 19, the chain wheel 17 of the shaft 4-? being fixed to the shaft, whilst the chain wheel 18 of the shaft -18 is free on such shaft and is connected by a sleeve #28 to the pinion 50 which is meshed with a driving pinon 51 secured to the countershaft 29. This arrangement causes the positive driving of the shaft 47 in a direction which will make the underside of the conveyor deliver rearwardly.

The wheels 12 and 13 can be adjustably attached to the table, any of the well known adjusting mechanisms being used for this purpose. The arms 6 and 7 can also be at tached adjustably to the side of the frame 1. I have not considered it necessary to enter into the details of such adjustments as such are well known.

In order to better understand the invention I will now describe its operation, assuming that it is drawn ahead by draft animals attached to the front end of the frame 1, so that the standing grain on the field is presented to the cutting blades.

In the advancement of the machine the cutter is driven and the cutting knives which are rotated, acting in conjuetion with the cutting blades, effect the cutting of the grain and the grain being bent towards the table by the deflectors falls thereon. As it falls on the disc it is guided into a more or less radial position by the wedge shaped dividers and as the disc rotates the grain is presented to the prongs which gather it up oil the table. The conveyor catching the grain gathered by the prongs forcibly drives it backwardly on to the deck which discharges it from the machine at the back in windrows.

Whilst I have entered into a detailed description of the various parts it will be readily understood that these could be read ily modified without in the least departing from the spirit of the invention as set forth in the accompanying claims.

lVhat I claim as my invention is 1. In a machine of the class described, a stationary arcuate cutting bar presentin a plurality of similar extending cutting blades, a rotatably mounted driven disc, a plurality of similar cutting knives secured to the edge of the disc and adapted in the rotation of the disc to sweep over the cutting blades and cut the standing grain as the machine advances, means riding the face of the disc adapted to gather and pick up the grain falling on the disc after being cut by the knives and means for discharging the collected grain from the machine.
